You need to get tested before you know for sure you have Fibro, so make sure you run through all of the possibilities of other things it could be before deciding you have it. No matter what the doctor says, stay away from them. This leads to physical dependence on something that is, in turn, making your body weaker and sicker. They can make you feel a whole lot better fast, but all they are doing is stimulating your adrenal glands, which does nothing at all for the underlying issues of your symptoms, and if taken for any length of time at all they basically destroy the ability of your adrenal gland to function.
